Together with the right firmware (see below) this gives the fully functional alternative of the Naza GPS module.

To make things easier I've created an Arduino Pro Mini shield (v0.4). It fits nicely under the Arduino board and make the setup easy and compact. It has GPS and compass connectors on one end plus the Naza connector pins on the other. You can build this shield yourself, the design is shared on OSH Park:https://oshpark.com/shared_projects/Ehm2RZPY

The firmware HEX file necessary for the adapter to work you can find attached to this post. You'll find upload instructions here.

Note that it IS NOT meant for commercial use. You can download the firmware and use it, you can download and modify the PCB design and build the boards for yourself, but anyone selling it will violate this only restriction that I have.

Although I've assembled two batches of adapters that I was able to offer to people they are all gone now. I do not have any more to offer and I do not plan to make any more. Please do not send me any PMs to request them!

Here are videos that that show a first prototype it in action on the ground...

The latest adapter prototype version is 0.4 (picture attached). Below you will find some step by step instructions on how to prepare and use it.

Finding the right GPS/compass module
In order to use this adapter you'll need a Neo 6M or Neo M8N (M8N support added in firmware 20150424) and HMC5883L compass combo. This post collects the ones that have been confirmed working with the adapter:https://www.rcgroups.com/forums/show...&postcount=434

GPS/compass module orientation
Once you did the modification you need to find the correct orientation of the module. While the original Naza module has its front marked with an arrow (and this is crucial for the module to operate correctly), the Chinese modules usually don't. This post explains how to solve that problem:https://www.rcgroups.com/forums/show...&postcount=134

Connecting to the flight controller
When the module is oriented correctly you need to connect it to your flight controller. This post explains how to do it properly:https://www.rcgroups.com/forums/show...&postcount=419Be very careful - incorrect connection can burn your adapter/GPS module

thats great im so excited for your findings and whenever youll able to release your first batch.
Not only will be a cheap replacements but also might be able to use even better gps than stock like that neom8 people are using with pixhawk

NAZA canbus to GS

Hi Mr. Pawelsky
I have used a canbus interface to plug straight to my naza PMU V2 .
wired it to USB FTDI interface and get those data on mission planner software.
To go further on mission planner what do i need to do ?
On naza ground station software i also get the dialogue box error
Any help would be appreciate
